Background
After several years of intensive research and development, perovskite solar cells (PSCs) are transitioning into the initial phases of commercialization in 2026. Their inherent advantages—lightweight, thinness, flexibility, and high-efficiency potential—position them to unlock new markets previously inaccessible to conventional silicon-based solar cells, such as curved roofs, building facades, and electric vehicle bodies. Against this backdrop, companies worldwide are accelerating not only technological development but also concrete strategies for mass production and market entry.
Key Findings / Results
As of 2026, the perovskite solar cell industry is characterized by active developments in two key areas: “commercialization” and “manufacturing equipment development.” A notable example in commercialization is Japan’s Sekisui Chemical Co. Ltd., which commenced commercial sales of its film-type perovskite solar cell, “SOLAFIL,” on March 27, 2026. While SOLAFIL offers an efficiency of 15% and a durability of 10 years, its lightweight and flexible properties enable the integration of solar power generation in previously unutilizable spaces. In terms of international competition, China’s LONGi set a high-efficiency record of 34.85% in 2025, maintaining a technological lead. Concurrently, the UK’s Oxford PV began commercial shipments in 2024, indicating broader global market penetration. Beyond the efficiency race, Japan is strategically focusing on “application differentiation,” leveraging perovskite’s unique attributes for markets like Building-Integrated Photovoltaics (BIPV) and agrivoltaics. Furthermore, Japan’s domestic iodine resources are recognized as a strength for economic security. In the manufacturing equipment sector, Japanese inkjet printer manufacturers such as Seiko Epson, Ricoh, and Konica Minolta are utilizing their expertise in solution-based processing and encapsulation technologies to play a crucial role in large-area production.
Technical Significance & Outlook
The commercialization momentum of perovskite solar cells is set to introduce new competition and innovation into the renewable energy market. Products like Sekisui Chemical’s SOLAFIL, due to their unique properties, are poised to become “location-agnostic” solar cells, facilitating energy supply in diverse installation environments. This is expected to significantly contribute to urban energy self-sufficiency and the proliferation of distributed power sources. Global technological competition will intensify, with Chinese firms excelling in high efficiency and cost-competitiveness, European and American firms pursuing first-mover advantages in specific markets, and Japanese firms leveraging niche applications and manufacturing technology. The role of manufacturing equipment suppliers is also critical, with Japan’s precision processing technology potentially becoming a key determinant of perovskite’s mass production quality and cost-effectiveness. Future challenges include further enhancing product efficiency, ensuring long-term durability (particularly guarantees exceeding 20 years), and compliance with international certification standards. This dual-structure evolution represents a crucible for perovskite solar cells to truly become societal infrastructure, and its trajectory will continue to be closely watched globally.
